24 Claims.

The present invention relates to ophthalmic mountings-and more particularly to mountings of the type in which non-metal lens rims are connected together by a metal bridge and are provided with metal end pieces.

When either of the non-metal of such a mounting, as at present constructed, becomes broken, as frequently happens during heating and stretching to mount the lenses in the rims, it becomes necessary to discard the whole mounting, which thus becomes a total loss. If one of the rims, furthermore, becomes damaged, or if the style changes from one type or shape of rim or bridge or end piece to another, the vwhole mounting must be thrown away.

An object of the present invention is accordingly to provide a new and improved mounting of the above-described character in which the end pieces and the bridge are detach-ably secured to the rims. The damaged or unstylish part may then be readily replaced by a like new part. The optician is, furthermore, permitted to keep a smaller stock on hand, since all that he needs to have is an assortment of be connected to any desired type of rims. Ac-

cording to the preferred embodiment of the invention that is illustrated and described herein, the bridge may readily be unscrewed from the rims and another bridge replaced; and metal pieces are detachably superposed over the nonmetal end pieces of the rim.

Other objects of the invention will be made clear in the course of the following description, taken in connection with the accompanying drawing, and will be defined in the accompanyingclaims.

The invention will be explained in connection with the accompanying drawing, in which Fig. 1 is a front elevation of an ophthalmic mounting constructed according to a preferred embodi' ment of the present invention; Fig. 2 is a fragmentary plan of the same; Figs. -3 and a are enlarged fragmentary sections taken upon the lines 3--.3 of Fig. 2 and 4--4 of Fig. 3, respectively, looking in the directions of the arrows; Fig. 5 is a rear view of a modification; Figs. .6 and 7 are enlarged sections taken upon the lines 6-56 and. 1..'l, respectively, of Fig. 5, looking in the directions of the arrows; and Fig. 8 is a section similar to Fig. 4 of a further modification. 7

The ophthalmic mounting of the present invention comprises, in its preferred embodiment, illustrated in Figs. 1 to 4, two non-metal, lensholding 2 and'A each having a non-metal end piece I, connected together by a metal bridge and having temples 6. Rearwardly pIOf jecting, non-metal guards 3 may be cemented to the rear faces of the rims 2 and 4, as illustrated more particularly in Figs. 4 and 8.

The bridge is providedwith an intermediate, raised portion i6, and two terminal or-endportions l8 -and'20 depending from the raised portion I5. bridge are secured to and in front of the rims. This may be 'effected'in anydesired manner. According to the preferred. embodiment, illus-' trated in Figs. 1 to 4, the end portions 18 and 20 .are each provided with transversely dis- 15 posed, integral lugs 22 and 24 that are received, respectively, in corresponding transversely disposedopenings 8 and Hlin the rims. Theopening 10 is preferably closed at M, the lug 24 merely fitting therein. The opening 8, however, is shown as extending transversely through the rim, from face to face thereof, in 'order that a screw 25 maybe threaded from the rear into an internally threaded opening 28 provided in the lug 22. ,If desired, the screw maybe 25 threaded in from the front, as shown in Fig. 8, in which event the terminal portions i8 and 20 of the bridge will be provided with screw-receiving openings 2-5. ,In that event, an internally threaded metal piece 23 may be set in place between the rim and the guard 3 before the latter is cemented to the former, so that the metal pieces 23 become integrally "secured in place.

The screws 26 cooperate with the lugs 22 and 24 to secure the bridge to the rims. 'If desired, additional securing means may be provided, though found to .be unnecessary,- in practice. One such additional means is illustrated in Figs.'5 and 6 as further, internally threaded lugs 21 at the junction between the raised por- 40 tion 16 and the end portions 18 and 26, and cooperating with screws 29. V A washer 3| may be interposed, as shown in Fig. 6.

The bridge may further be provided at the junctions between the intermediate portion I6 and the end portions I8 and 2G with integral U-shaped portions lfi, also illustrated in Fig. 5, into which fit projections or lugs 48 of the rims 2 and 4. The projections 48 extend out from the peripheriesof the respective rims 2 and 4 in 50 substantially the planes of the respective rims. The neck 50 ofthe U may form a pleasing, metal-front, continuation of the bridge, in the front plane of the bridge, and extending over the projections or' lugs 48, which are. fitted into The end portions I8 and 20 of the 10' the U from the rear. The arms of the U extend rearwardly from the neck 50 substantially at 7 right angles to the said front plane of the bridge.

The metal bridge is thus efiectively secured to the rims, though it is detachable therefrom merely by loosening the screws.

Each bridge portion l8 and 20 maybe further provided, near its extremity, with an additional internally threaded lug 33, more or less like the lug 23, cooperating with a screw 35, like the screw 29, as is also illustrated in Fig. 6.

A metal end piece 52 may be superposed over I each end piece I, so as to harmonize with the metal bridge, and the temples 6 will be pivoted to the metalend pieces. the bridge, are detachable, According to the preferred embodimentof the invention, the end pieces are U-shaped, as shown more particularly in Fig. '7, the non-metal end piece I being-received in the U. One side of the U may have an integral, internally-threaded lug 54 extending into the non-metal end piece I, ascrew 56 being threaded into the lug from the rear of the end piece I to secure the metal end piece 52 detach-1 ably to'the non-metal end piece I. A screwthreadedsleeve 58 may be inserted into and half through the non-metal endpiece i, and is provided with a knurl or other projection or projections to keep it from'turning. A screw 60'is screwed into the sleeve 58 to help hold the parts together. V a

It will be understood that the invention may i be further modified by persons'skilled in the art,

and such modifications are considered to be within the spirit and scope of theinvention as defined in the appended claims.
